SASH CONSTRUCTION Filed March 5, 1930 Patented Apr. 17, 1934 UNITEDSTATES PATENT OFFICE SASH CONSTRUCTION William S. Hamm, Eikart, Ind.,assignor to The Adlake Company, Chicago, 111., a corporation of IllinoisThe present invention relates to sash construction, and has to doparticularly with an improvement in the weatherprooflng of street carand motor bus windows.

The primary object of the invention is to provide novel pile fabricweather strips on the sides 'of the sash for sliding coaction with thesides of the guides.

Another important object of the invention is to provide guides havingnovel side faces for coaction with soft, readily conformable weatherstrips on the sides of the sash.

While the foregoing statements are indicative in a general way of thenature of the invention, other objects and advantages will be recognizedupon a full understanding of the construction, arrangement and operationof the improved weather strips and guides.

In order that the invention may be readily 20 understood, one form ofthe same is presented herein, but it will of course be appreciated thatsuch form is chosen merely for the purpose of exempliflcation and thatthe invention is capable of being embodied in other structurallymodified forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. l is a vertical section through a window equipped with the weatherstrips and guides of the invention;

Fig. 2 is a horizontal section through one side of the sash and windowframe; and

Fig. 3 is a fragmentary perspective view of one of the guide members.

The weatherprooiing feature which constitutes the subject matter of thisinvention is shown in the drawing as applied to a sash 10 of thesocalled drop type. The sash is mounted in a frame 11 and is slidablevertically in upright guides composed of outside strips. 12 and insidestrips 13 carried by the frame.

When the window is closed, as shown in Fig. l, the top rail 14'of thesash is sealed outwardly against the header 15 of the frame by a strip16 of pile fabric, which strip is attached to the top rail with the pile17 of the fabric projecting outwardly into engagement with a plate 18,and the bottom rail 19 of the sash is sealed both inwardly and outwardlyagainst the edges of the drop 50, slot 20 in the sill 21 of the frame bytwo similarly mounted strips 22 and 23 of pile fabric. The sash is heldin the position shown in Fig. 1 by two locks 24 of the so-called rockertype which are attached to. the inner face of the top rail 14 adjacentthe ends of the latter. The locks are characterized by pivoteddownwardly projecting cams 25 which swing inwardly when released andwedge against inclined steps 26 on two racks 27 which are set into theinner guide strips 13.

When the window is to be opened, the cams 25 0 of the locks are swungoutwardly far enough to clear the steps 26, after which the sash islowered into the slot 20, where it is held'in either a partially loweredor a fully lowered position by engagement of the cams 25 with certainother of 05 the steps 26.

The sash is provided, on the outer faces of the side stiles 28 of thesame, with two strips 29 of pile fabric, which strips are arranged withthe pile 30 thereof projecting outwardly into engagement with the innerfaces 31 of the outer guide strips 12, which guide strips, in theparticular form shown, are of hollow double walled construction. Thefaces 31 of the guide strips are provided with a number of closelyarranged apertures 32 into which the pile of the fabric will extend whenpressure is brought to bear thereon. The engagement of the pile with thesides of the apertures serves to hold the sash firmly against sidewisemovement when locked, and also keeps an the pile combed clean ofcinders, dirt and other foreign matter, which foreign matter can passthrough the apertures into the hollow interiors of the guides. Insteadof providing apertures in the faces 31, the latter may be corrugated in3 either or both directions or provided with small closed or openindentations or projections capable of producing somewhat the sameinterlocking effect. The plate 18, which is engaged by the pile 17 ofthe strip attached to the top so rail of the sash, may also be aperturedor otherwise deformed for the same purpose.

The outwardly wedging action of the cams 25 of the locks serves to pressthe outwardly projecting pile of the top, bottom and side strips snuglyand firmly against the opposed frame and guide surfaces into tight,noiseless weatherproofing association therewith, and such pressure maybe supplemented at points below the locks by spring-pressed followerdevices (not shown) of well known construction acting outwardly againstthe sash.

' The weatherproofing strips 16, 22, 23 and 29 are of extremely simpleyet durable construction. Each of the strips is structurally like the108 one shown in Fig. 2, and includes a thin flat backing plate 33 ofsheet metal having reversely bent marginal flanges 34 which extend aboutand clamp the side edges of the strip 29. The side edges of the strip 29are preferably selvaged or no woven free from any of the pile in thecourse of manufacture. The attachment to the sash is preferably effectedby screws which extend through apertures in the strip and are embeddeddeeply in the pile with their heads substantially flush with the edgeflanges 34 of the backing plate.

I claim:

1. In sash construction, a vertically slidable sash, guides for thesame, and strips of pile fabric attached to the sides of the sash withthe pile projecting outwardly therefrom into engagement with the sidesof the guides, said guides being provided at intervals with depressionsinto which opposed portions of the pile on said strips will extend.

2. In sash construction, a vertically slidable sash, guides for thesame, strips of soft yieldable material attached to the sides of thesash for engagement with the sides of the guides, and means for pressingthe strip-faced sides of the sash against the sides of the guides, saidguides being provided at intervals with depressions into which opposedportions of said strips will extend.

3. In sash construction, a vertically slidable sash member, and astationary guide member for the same, one of said members being providedwith a longitudinally extending strip of soft yieldable material, andthe other of said members being provided on its opposed face withrecesses into which portions of said strip are adapted to extend.

4. In sash construction, a vertically slidable sash, guides for thesame, and vertically extending strips of sealing material attached tothe sides of the sash for engagement with the sides of the guides, saidguide being of hollow construction and being provided with apertures inthe faces thereof hich are engaged by the sealing strips.

5. In sash construction, a vertically slidable sash, guides for the samehaving interrupted surfaces, vertically extending strips of sealingmaterial attached to the sides of the sash for engagement with theinterrupted surfaces of the guides, and means for supporting the sash inan elevated position in the guides, said means serving to force portionsof the sealing material into the interruptions in the surfaces of theguides,

whereby to prevent sidewise or upward movement of the sash upon thewindow being subjected to jarring forces.
